Technology centre promotes next-step welding


In line with the company’s global drive, Lincoln Electric is in the process of setting up a new welding technology centre in Midrand, Gauteng.

“We have always had workshop space in this facility, but we are now installing a permanent demonstration centre to allow us to promote our full range of welding solutions,” says Benoit Lamotte, regional manger for sub-Saharan Africa and the Indian Ocean.

“We have the machines, the consumables and the welding knowledge to enable us to bring the best of the world’s productivity solutions to local customers. We are striving to move people up the technology ladder, from wherever they are. All the next-step welding solutions in this centre target productivity: increased deposition rates; higher duty cycles; and reduced grinding and cleaning times after welding, for example,” Lamotte tells Cape Business News.

“In South Africa, for example, we are promoting Tandem submerged arc welding with ac/dc machines as a step up from traditional single wire dc submerged arc systems. Tandem sub-arc welding offers with Lincoln PowerWave ac/dc power sources significantly higher productivity and process control, which can result in much lower total costs of production,” he explains.

Another key focus for Africa is pipeline welding. On display is Lincoln Electric’s STT solution for root welding and its mechanised flux-cored welding systems, which use Lincoln BUG-O solution.

“For pipe welding work, we want to move people away from using solid GMAW wire to using flux-cored and metal-cored wires, which offer higher deposition rates. And to replace stick welding (SMAW) we are showcasing the advantages of using Innershield gasless flux-cored wires as a substitute,” Lamotte says, adding that these wires are ideal for site-based work in Africa, where shielding gas is not always readily available.

Aluminium welding also features, “We aim to move people away from using 1.0mm wire to using 1.2 or 1.6mm wires, even on thin plate. This can be achieved using pulse, pulse-on-pulse and other advanced waveforms available from PowerWave power sources.”

Introducing Lincoln’s ‘True Energy’ platform for the more accurate monitoring of heat input on highly responsive, modern inverter-based welding machines, Lamotte says that the welding of modern materials, such as duplex and super-duplex stainless steels, requires careful attention to weld-metal metallurgy.

“Many of today’s applications require very tight control of heat input, for example. Through True Energy and Production Monitor, we are able to embed high levels of monitoring and control into the PowerWave product range to simplify the task of achieving good quality welds in complex materials,” he assures.

Keeping abreast of the Internet of Things, PowerWave machines can be allocated an IP address and directly connected to the Internet, allowing them to be remotely monitored and/or controlled. Productivity and welding parameters can be monitored in real time or downloaded on a daily weekly, or monthly basis.

“It’s all about productivity,” he reiterates. “We welcome customers at all levels of sophistication to visit us at this new centre, where we will strive to develop better welding solutions for any application,” he concludes.
